HIV-infected participants
HIV-infected participants taking lopinavir/ritonavir (Kaletra) and one other protease inhibitor. Lopinavir/ritonavir (Kaletra) dosing and administration according to the Summary of Product Characteristics (three 133 mg/33 mg capsules twice daily or two 200 mg/50 mg tablets twice daily). |

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of Participants With Human Immunodeficiency Virus -1 Ribonucleic Acid (HIV-1 RNA) <50 Copies/mL
Time Frame: Baseline (Week 0), Weeks 4, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144
|
Viral load (number of HIV-1 RNA copies in the blood) was measured at baseline and scheduled study visits.
A decrease in viral load is a measure used to assess the effectiveness of antiviral treatments.
The percentage of participants with HIV RNA less than 50 copies/mL at each time point is presented.

|
Increases in CD4 count are a biomarker for antiretroviral treatment effectiveness in restoring immunologic function.
Changes in participants' CD4-positive (CD4+) T-lymphocyte counts were assessed by measuring the change from Baseline in the number of CD4+ cells at scheduled study visits.

The CD4/CD8 T-cell ratio, also known as the T-lymphocyte helper/suppressor profile, presents the number of lymphocytes in the blood positive for CD4 cells compared with the number positive for CD8 cells.
Changes in participants' CD4/CD8 T-lymphocyte ratio were assessed by measuring the change from Baseline in the ratio at scheduled study visits.
